BRIEF SUMMARY OF THE INVENTION

The object of the present invention to provide a saw bench, with which alarge variety of material types to be cut can be sawn and for a user ofthe saw bench the sawing process is safe and trouble-free.

The above object is achieved by a saw bench comprising a first pair oflegs; a second pair of legs; at least two cross members for material tobe cut are arranged between the first pair of legs and the second pairof legs; a first abutting element and a second abutting element areprovided with each cross member and being arranged at an angle withrespect to each other; a kerf is defined between the cross members; andat least a first guide rail and/or at least a second guide rail for asawing member is mounted on the saw bench in such a way that, duringsawing of the material to be cut, the sawing member reaches through thekerf below a level of the material to be cut.

According to the invention each cross member comprises a first abuttingelement and a second abutting element is arranged at an angle withrespect to each other. A kerf is defined between the cross members. Inorder to ease the sawing process, at least a first guide rail and/or atleast a second guide rail for a sawing means is mounted on the saw benchin such a way that, during sawing of the material to be cut, the sawingmeans reaches through the kerf below a level of the material to be cut.

The first guide rail is mounted to the frame at the backside. For a safecutting, a guide pin is attached to the sawing member, so that thesawing member is slidably guided in the first guide rail. The firstguide rail is provides with a holding fork at which the sawing means canbe parked after the sawing process. The second guide rail is mounted tothe frame at the backside of a second abutting element. A guide pinwhich is connected to the sawing member, in which is slidably guided inthe second guide rail. On the second guide rail, a holding fork ismounted, on which the sawing member is parked.

Furthermore, a rocking device can be mounted to the frame in areceptacle at a free end of the second abutting element. A guide pin isconnected to the sawing member and is slidably guided in a guide channelof the rocking device. On the rocking device, a holding fork is providedat which the sawing member is parked.

At a free end of the first abutment element and/or at a free end of thesecond abutting element at least one take-up is provided in which theholding elements are pluggable for holding elements or the timber to becut. Each holding element is provided at least one pin, which engages ina form-fitting manner in order to mount the holding element in thereceptacle.

The legs of the first pair of legs and the legs of the second pair oflegs are each rigidly connected together such that the legs of each pairof legs are arranged at an acute angle.

The two pairs of legs and the cross members for the pieces to be cut arerigidly fastened to a frame of the saw bench. The frame of the saw benchmay be associated with four rigid base supports, which are not adjustedin height. The base supports have slides mounted at opposite ends, sothat the saw bench can be moved easily. According to a furtherembodiment of the invention the four floor supports are heightadjustable. This allows the equalizing on uneven ground.

At least one extension module is detachably connected to the frame ofthe saw bench. Depending on the type of the extension module two rigid,not height adjustable floor supports or two height adjustable floorsupports are mounted.

To increase the comfort of use of the saw bench, a wheel can be attachedto the saw bench. The wheel is adjustable in height by means of amechanical crank. Similarly, two driving handles can be inserted intocorresponding slots on the frame of both directions. The driving handlesare parked in appropriate positions on the frame and do not disturb theworking process when the saw bench is in use.

The first abutting element and the second abutting element have severalsecuring elements for the material to be cut, so that any slipping ofthe material to be cut is avoided.

The basic idea of the inventive multi-functional saw bench is theexpansion to several versions which have different working lengths. Themodel “beginner” measures 800 mm, the model “standard” measures 1000 mmand the model “professional” has a working length of 1300 mm. Forexample if firewood (maximum diameter 33 centimeters) or any othermaterial which to be cut, the support has cross members that are weldedon a sturdy frame made of square tube elements. The cross members havedifferent widths and are separated kerfs (width about 10 centimeters).The user can saw the material to be cut with a motor chain saw orelectrical saw vertically from above. The cut is directed to one of thekerfs. These kerfs are arranged so that the users saw the material to becut completely through and the sawing member passes, due to the kerfs,substantially below the level of the on the cross members.

Thus, the wood or the material to be cut does not fall off the saw benchbefore or after the sawing process, on both sides of the support formedby the cross members, holding elements are provided, which are also madeof a tube with rectangular form. These support elements are mounted tothe framework of the saw bench. The support elements can also bearranged arbitrarily and can also be parked below the support surface indesignated elements. So they always remain available on the saw bench,can be secured by bolts and do not get lost. The support elements aresuitable not only for bundles of firewood, but also for the branches,round timber or boards. Also curved can be tamed with the inventive sawbench. Twist locks prevent a turn away especially of round wood at thetime of sawing. Additionally, the cut wood remains on the saw bench as apackage and can be removed from the saw bench as a whole.

So that the user does not have to cut freehand, the saw is used togetherwith at least one guide rail on the frame of the saw bench. Thus, atilting of the sawing member or a sawing into the cross members can beprevented. The guide rails are slightly inclined inwards, whichfacilitates the sawing process and supports the natural sawing motion. Aguide pin, for example a chain cover nut of a chainsaw, provides thenecessary guidance of the chain saw in the guide rail.

Another advantage is that the guide rails mark the respective cut at theposition of the saw kerfs. The mounted or mountable guide rails,however, highlight the correct cutting position clear and unmistakable.For a better distinction all pluggable, i.e. removable parts on the sawbench are painted in the signal color orange. In addition, after eachsawing, the saw can be suspended in a holder, which is connecteddownstream of the guide rail. The saw is then in a cleared position.

So that the saw bench can be easily moved, a chassis is provided, whichconsists of a wheel, which is adjustable in height by means of amechanical crank. With the height adjustment of the wheel a groundclearance of up to 25 centimeters is be provided. The wheel can beattached at both sides of the saw bench. Also two handles can beattached in either driving direction and can be parked on the frame ofthe saw bench.

The length of the saw bench can be extended with extension modules. Eachextension module can be docked bay at least three connectors to the sawbench to be extended. It is also possible that the saw bench is providedwith four height-adjustable floor supports to compensate for uneventerrain. The sawing with a hacksaw, so with pure muscle power is alsopossible. The hacksaw can be guided by one of the guide rails during thecutting process.

According to a further embodiment the saw bench comprises a first pairof legs and a second pair of legs. At least two cross members formaterial to be cut are arranged between the first pair of legs and thesecond pair of legs. A first abutting element and a second abuttingelement are provided with each cross member and being arranged at anangle with respect to each other. A kerf is defined between the crossmembers. A rocking device for a sawing member is mounted to the secondabutting element of the saw bench. The rocking device and a securing pinensure a safe cutting process for motor, hydraulically or pneumaticallydriven sawing members. After cutting through the material remains on thesaw bench and a slip off of the material is avoided. The securing pin isprovided with the sawing member and is slidably guided in a guidechannel of the rocking device. A holding fork is mounted to the rockingdevice in order to park the sawing member after the sawing process.
